Treatment

Trifurcula guercheae Varenne & Nel, 2019: 88 , figs. 11–16.

Examined material. Holotype Ƌ: France, Alpes-Maritimes , Isola-sur-Tinée, 1670 m, uv, 11.VII.2018, Th. Varenne leg., genitalia slide TV n°6770 ( RCTV).

BOLD Specimen ID TLMF 27069; BOLD Sequence ID LEASV317-19.

BIN: none

Identity: Trifurcula guercheae Varenne & Nel, 2019 , identity uncertain.

Remarks. Trifurcula guercheae was described from a male holotype and briefly compared with Trifurcula immundella (Zeller, 1839) and T. beirnei Puplesis, 1984 (Varenne & Nel 2019). Both are indeed rather different species, but the genitalia of T. guercheae are almost completely identical to T. pallidella (Duponchel, 1843) (van Nieukerken & Johansson 1986; van Nieukerken et al. 2004b), a species currently unknown from France, although it is found in the Ligurian Alps not far from the French border (van Nieukerken et al. 2004b).

A short DNA barcode sequence of 406bp of the specimen is about 3% divergent from T. pallidella (Duponchel, 1843) , the nearest known neighbour in BOLD. For the time being we refrain from synonymising T. guercheae , as further material is needed to assess the barcode variation in T. pallidella .
